Introduction: Potty Training Aid

Having trouble motivating your toddler while potty training them? Well, I have the answer for you, the Potty Training Aid. After each time your toddler uses the potty correctly they push a button to celebrate their accomplishment. The Potty Training Aid will play a song and light an array of lights. This is a can be a little tricky to set-up, but if you take your time you will be able to complete this project.

Step 1: Materials


Ardunio Uno

USB Cable

15 Male-Male Jumper Wires

9 - 330 Ohm Resistors

8 - LEDs

1 - Push Button

1 - Piezo Buzzer

Step 2: Hooking Up the Components

Connect the materials as seen in the pictures above.

The piezo buzzer is much larger in the digital diagram.

Helpful Hints:

The Piezo Buzzer is polarized and can only be connected to a circuit in one direction.

The LEDs are also polarized and can only be connected to a circuit in one direction. I found it helpful to have all the LED anodes facing the same direction.

Step 3: The Code

Here is the link to the code.

Most of the code I used was inspired by's SIK Experiment Guide for Arduino - V3.2. If you would like to see how each component is set up you can go to this link.

Step 4: The Finished Product

Time to test your finished potty training aid. If everything is set up correctly the 8 LEDs will light up quickly and then a song will start to play.
